Video Information
See the container, codecs, resolution, frame rate, bitrate and identifying tags (location, device, dates) of a video. The file is read on your device and never uploaded.

The video is processed on this device and never uploaded.
MP4, MOV, WebM, MKV, AVI, WMV, FLV, 3GP, TS / MTS / M2TS or VOB / MPG
Files over 1 GB can be slow. Very large outputs need a browser that can save straight to a file.

Browser and Tool Capabilities
Which codecs this browser can handle itself, and which the FFmpeg.wasm fallback adds.
FFmpeg.wasm runs on the CPU. It is slower, but reads and writes many more formats.
Video Codecs (19)
Audio Codecs (16)
Container Formats (15)
Performance Information
Mediabunny uses the browser's WebCodecs encoders and decoders and is typically 5 to 10 times faster than FFmpeg.wasm. FFmpeg.wasm handles more codecs but runs entirely in software (WebAssembly).
How it works
Choose one or more videos. The page reads each file's headers in your browser and shows the details in tabs: the container, duration and size; the video codec with its profile and level (for example H.264 High, level 4.1, or HEVC Main 10); resolution, aspect ratio, frame rate and average bitrate; the colour space and HDR format (HDR10, HLG or Dolby Vision); the audio; timing; and identifying tags such as GPS location, device model and dates.
The capabilities panel checks which codecs this browser can decode and encode with WebCodecs, so you can see why a file will not play here or which output codecs are available. Nothing is uploaded and the video is not changed.
Supported files
- Inputs
- MP4, M4V, MOV, WebM, MKV, AVI, WMV, FLV, 3GP, MPEG-TS (TS, MTS, M2TS) and MPEG-PS (VOB, MPG).
- Outputs
- None. The file is only read, and details it does not record, or this browser cannot read, are shown as not available.
Limitations
- Profile, level, colour space and HDR format are what the file signals. A file that signals nothing shows them as not available.
- The bitrate is the file average (size divided by length) and includes the audio and container overhead.
- For containers the browser cannot read itself (AVI, WMV, FLV, VOB) the profile, colour and tag details are not available.
